condition: excellent

This Yamaha PSS-680 is in good working condition, and includes a power supply. I tested it, and everything appears to be working normally, and sounds nice. Even though it's categorized as "toy keyboard" it still has a real programmable FM synth as its sound engine, and you can get some nice, fairly complex FM tones from this. The synth uses the Yamaha YM3420 FM sound chip that was used in a number of Yamaha keyboards of this era, and on this keyboard you have access to some of the FM parameters (frequency, ratio, etc.) It also has midi in, out and thru, which is pretty rare on this type of keyboard. There's a little bit of cosmetic wear, but overall it's in very nice condition for its age. Price is firm at $100 (these tend to sell for a little more online). Serious inquires only, scammers beware (I'll share my phone number after an initial e-mail).
